PROJECT NOTES

As a result of the success of the Aubin Grove train station project, Peritas was again engaged to provide temporary works engineering for the new Mandurah traffic bridge. The bridge has a curved soffit in section and also curves along all three axes along the span, making this task truly challenging. Our engineers devised an innovative approach of designing reusable steel forms, comprising 3 soffit forms on hydraulics, 2 internal traveller forms with hinges and hydraulics on rails that launched with the bridge before being withdrawn onto the following soffit and 2 external forms. We also performed the steel shop detailing on this form to ensure that our requirements were satisfied.
